A Description Logic for Unifying Different Points of View

Abstract:

Multilevel modelling is the conceptual modelling problem of having concepts that could be instances of another concepts. It is a relevant problem for many areas and in particular for ontology design. We motivate our work by a realworld case study on the accounting domain in which the points of view of expert and operator users are conceptualized as two knowledge levels. In this paper we address theoretical aspects of extending the tableau algorithm for a description logic that enables unifiying different user perspectives in a multilevel knowledge modelling, following a Henkin semantics.
